   The engine is spewing oil from the sides of the engine. This is causing overheating and check engine light to come on. Mechanics cannot get an error read on it. There is no oil leak coming from under the engine.

   The Car has over the last few years not turn off due to shift to park. This is concerning, due to we cannot turn the car off unless we strike the shifter few times assuming this is the remedy. It doesn't look like there is any type of recall but there should be.

   My car will not park. I get a shift to park error message. I tried restarting and shutting it off. Didn't work. I ended up putting it in neutral turning on the emergency brake and then shutting the car off. I have had no problems with this car to this point, I am a single car owner and my car must be reliable. I can't spend a half hour trying to get the car to shut off.

   When I’m driving a warning comes on my DIC screen that says “ACTION REQUIRED STEERING ASSIST IS REDUCED DRIVE WITH CARE”. The AC does not work and the temp gauge goes to cold with the radiator fan blowing at full speed. My car has done this since I purchased it used in 2019 and when I call dealer they say there is no recall and $1200-1800 to replace a sensor and thermostate. I have not had the issue fixed yet.
